Do not purchase Oclean products!!!
I purchased the Oclean X Ultra S Sonic toothbrush less than a year ago. I am getting subpar battery life. It has been that way since day one. I thought that it might get better after using it for a while, but it has not. I wrote to their customer service and they basically told me oh well sorry for you. That toothbrush is advertised on their web site to get up to 40 days on charge. Well I also owned their Oclean X Pro and that was advertised to run up to 30 days. In used the same settings on both toothbrushes and i was able to get 30 days from the older toothbrush which is now about 2 or 3 years old and still holds a charge for 30 days. I thought that I was purchasing an upgrade to my older one and it turns out I was not. I can barley get 20 days per charge and they told me that there is a 15-20% loss allowed, but I am clearly loosing 50%. They offered to send me 2 new toothbrush heads. They are useless and do not stand behind their products so for me I am now done with Oclean. Terrible customer service!!!
